我们以多年来不同类型水稻良种高产试验田及大面积水稻生产的有关资料,对水稻高产群体内个体营养器官与经济器官的相关生长规律,以及每穗粒数预测指标进行总结分析,并对水稻长穗期的看苗施肥技术进行了试验研究.现将主要结果整理如下:
Based on the data of different types of rice high-yielding experimental fields and large-area rice production over the years, we summarized the growth pattern of individual vegetative organs and economic organs in rice high-yielding population and the predictive index of grains per spike. The experiment of seedling fertilization at heading stage was carried out. The main results are summarized as follows:
